If I make database changes locally, and then use postgres with heroku, what does pushing the database actually do? Update schema, data, or both? There is no information on what actually happens when you push a database using the heroku toolbelt. I have a live production app that I don't want to overwrite data, but I have new unrelated tables and stuff that needs to be uploaded. Is there a good way to do this?
